Kicker springs and spring holders provide the 3rd rotation to the fixtures of Colt, Spear and TongS style. The holders are available for different kicker rod diameters 10 / 12 / 16 / 25 mm. Each spring holder has to be equipped with an exchangable spring. Than it is mounted from the side to a kicker rod. The spring should be of a length that it will approach the planet approximately tangential. Usually for flat gears (Spear, TongS) we recommend the wide (B-Type) springs and for high gears (Colt) the slim (M-Type) ones. Springs can be changed without tools.  

Many variants of kickers and springs are available directly from our shop!
